SPECIFICATION forming part of Letters Patem No. 775,825, dated November 22, 1904.

Application filed May 4, 1904;- Serial No. 206,389. (No model.)

1'11 all 1071/0117, it may concern.-

Be it known that I, WILLIAM H. KENDALL, a citizen of the United States, residing at Broolo lyn, county of Kings, State of New York, have invented new and useful Improvements in Attachments for Stamping-Presses for Holding Material While Pressing Hats, of which the following is a specification.

This invention relates to devices of the kind for which United States Letters Patent No. 715,084 were granted December 2, 1902. The disadvantage of this patent device is that the stock, such as mohair or other fabric, must be cut in sufficiently large pieces to cover the die for the vertically-descending clamp to come down onto and get a hold on the stock. As, however, this stock, such as mohair, which is generally used, is elastic, smaller piece of stock could be stretched to cover the die if clamps were provided which moved in over the die to catch the stock and then returned while grasping the stock to stretch the latter.

The invention for carrying out this object is set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is an elevation of a press with this invention applied thereto. Figs. 2 and 3 are views of a clamp. Fig. 4 is a plan view of a clamp. The remaining ligures show modifications.

The clamps in this case are not only ad justable or movable in vertical or lateral direction, but also made to move transversely to stretch the goods or stock. To accomplish this stretching of the stock by the clamps, each clamp instead of having its upright e directly connected to the foot it, secured at it to the bed-plate, has such upright a connected to piece on, hinged at a to the foot.

As seen in the drawings, each clamp 0 is composed of jaws which by a handle or lever (Z can be made to nip or take hold of the cloth or stock. The clamps are swung on pivots it inside the limits of die I) to take hold of a piece of goods or stock on the die. When the jaws have grasped the stock, these jaws are pulled or swung back about pivot a to stretch clamp is with one jaw or part say the upper Y one-shorter than the other, and the jaws ending, respectively, in tongue-and-groove form. The tongue entering the groove secures a firm hold or nip on the interposed stock, so that as the jaw moves out or the attendants pull out the jaws the goods or stock being stretched will not slip or get free. A clamp thus made even when closed or held shut'by hand maintains a firm grip.

As seen, the device can be made without springs, which is found advisable, as the absence of springs contributes to the durability of the device. The upper and lower grip or jaw working together on hinge-joints and locked by cam or eccentric, while not so simple as a hand-clamp, is nevertheless durable, reliable, and easily constructed. In case of a clamp locked by lever or cam (l the latter can be pivoted on a bearing part of the upper jaw and made to bear or act onto a projecting part of the lower jaw or grip. In case of a hand-operated clamp, Figs. 5 and 6, the rear of each jaw has a handle-loop which enables the operator to firmly close or hold the jaws, as also to give the requisite pull to stretch the stock. fore the attachment of upright or arm a can be swung so as to either extend above or be low the bed-plate, Fig. 1 or Fig. 6, thus allowing adjustment for the height or angle of the clamp. The bolt or slot connection between the piece at and upright a is useful, as explained in said patent, as by loosening the bolt i the upright 0 can be adjusted laterally or up or down. The pivot connection or support 0 can serve to set the clamp with respect to the upright, and after the jaw is there set or adjusted this bolto can be fixed or tightened. Each of the jaws shown in Figs. 7 and 8 has its main or center section c provided with pivoted or swinging end. or swing-sections 0', and as the corner or free parts of the stock are drawn into the press by the parts a 7) coming it may be noted that the piece m be together these wings a can swing from their straight or allned position to the edge or curve of the plunger or die 5.

What 1 claim as my invention, and desire to secure by Letters Patent, is

1. A stock-holding attachment comprising a clamping portion and lever, an upright or support on Which the clamping portion and lever are adjustably mounted, and a foot on which the upright is mounted to swing transversely.

2. A stock-holding attachment comprising a clamping portion and lever, and an upright for supporting the same and made vertically, laterally and transversely adjustable.

3. A stock-holding attachment comprising a clamping portion, an upright, a foot, and a transversely-swinging piece on the foot to Which the upright is connected.

4. A stock-holding attachment comprising a clamping portion, an upright, a foot, and a transversely-swinging piece on the foot to which the upright is connected by bolt-andslot connection so as to be vertically and laterally adjustable thereon.

5. A stock-holding attachment comprising a clamping portion, an upright, a foot, and a transversely-swinging piece on the foot to which the upright is connected said swingpiece being adapted to be swung above or below the foot. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
